Abstract: The present invention is directed to the radioligand compound, [35S]-radiolabeled (+)-N-[1?-(6-cyano-1,2,3,4-tetrahydro-2(R)-naphthalenyl)-3,4-dihydro-4(R)-hydoxyspiro[2H-1-benzopyran-2,4?-piperidin]-6-yl]methanesulfonamide. Also within the scope of this invention is a method for identifying compounds that bind to the IKr channel, and may have antiarrhythmic activity.

Abstract: The present invention provides polynucleotides and polypeptides of a human serine racemase. The polynucleotides and polypeptides are used to further provide expression vectors, host cells comprising the vectors, probes and primers, antibodies against the serine racemase protein and polypeptides thereof, assays for the presence or expression of serine racemase and assays for the identification of compounds that interact with serine racemase and transgenic animals expressing human serine racemase.

Abstract: A thrombin receptor antagonist having the formula useful for inhibiting the aggregation of blood platelets. The compounds can be used in a method of acting upon a thrombin receptor which comprises administering a therapeutically effective but non-toxic amount of such compound to a mammal, preferably a human.

Abstract: The present invention is directed to the radioligand compound, [35S]-radiolabeled (+)-N-[1′-(6-cyano-1,2,3,4-tetrahydro-2(R)-naphthalenyl)-3,4-dihydro-4(R)-hydoxyspiro[2H-1-benzopyran-2,4′-piperidin]-6-yl]methanesulfonamide. Also within the scope of this invention is a method for identifying compounds that bind to the IKr channel, and may have antiarrhythmic activity.

Abstract: A thrombin receptor antagonist having the formula 1

Abstract: Peptides having the general sequence A-B-C-D-E-F-Z wherein A is Ala, B is pFPhe, C is, for example, Arg, D is Cha, E is, for example, hArg, F is, for example, Tyr, and Z is, for example NH.sub.2. The peptides are useful for promoting wound healing and arresting bleeding in a patient.

Abstract: A sporting net which can be utilized either as a hockey net or a basketball hoop. The apparatus includes a center post having a basketball hoop and its upper end. Furthermore, two linkages are pivotally secured at opposing locations at the intermediate extent of the center post. A hockey net is secured in between these two linkages. In order to facilitate storage of the sporting net, the linkages are pivotal between a first use orientation, wherein they extend laterally from the post then downwardly to abut a recipient surface and a second storage orientation wherein they are positioned generally next to the post.

Abstract: The radioligands are six amino acid peptides having iodinated tyrosine at amino acid position six, including Ala-pFPhe-hArg-Cha-hArg-Tyr(I)-NH.sub.2, which mimic the activated form of the thrombin receptor protein. Thrombin receptor radioligands of the present invention are useful for screening for thrombin receptor antagonists.

Abstract: A protein which inhibits collagen-stimulated platelet aggregation. The protein has a molecular weight of approximately 17,000. A method of isolating the protein from Ornithodoros moubata and using the protein to prevent or delay blood coagulation by blocking the stimulation of platelet aggregation by collagen is also described. The protein is useful in the prevention, prophylaxis, therapy and treatment of thrombotic diseases.

Abstract: A protein isolated from crude Haementeria officinalis extract which blocks stimulation of platelet aggregation by collagen. The protein has a molecular weight of approximately 16,000. A method of isolating the protein and using the protein to prevent or delay blood coagulation by blocking the stimulation of platelet aggregation by collagen is also described. The protein is useful in the prevention, prophylaxis, therapy and treatment of thrombotic diseases.

Abstract: The invention comprises proteinaceous substances isolated from crude Ornithodoros moubata extract which inhibit adhesion of platelets to collagen. These substances do not inhibit platelet adhesion to fibrinogen, and are therefore particularly useful for inhibiting adhesion of platelets to collagen when simultaneous inhibition of platelet adhesion to fibrinogen is undesired. They are particularly useful in the prevention, prophylaxis, therapy and treatment of thrombotic diseases.

Abstract: A method for blocking platelet adhesion to collagen by contacting platelets with a polypeptide having one of the following sequences:NH.sub.2 (Ch) Ala Arg Gly Asp (Cx) COOH (i)NH.sub.2 (Ch) Ala Ala Gly Asp (Cx) COOH (ii)NH.sub.2 (Ch) Ala Arg Tyr Asp (CX) COOH (iii)NH.sub.2 (Ch) Ala Arg Gly Asp (Cy) Z (iv)wherein Ch, Cx, Cy are defined amino acid sequences or conservatively substituted amino acid sequences, and Z is NH.sub.2 or COOH.

Abstract: Microwave absorbers reduce radar cross-sections of airborne objects by attenuating reflectivity values. In Jaumann absorbers laminated layers are placed on the reflecting surfaces, the laminated layers being lossy layers separated by dielectric spacing layers. From the point of view of accuracy and reproducibility Jaumann absorbers have been difficult to construct. A mode of fabrication overcoming these difficulties is provided herein.
